以南方电网2005年丰大运行方式、贵广直流单极运行、天广直流双极运行为例，对东送输电断面的输送功率情况进行了研究。

The cross-section transient transmission limits of west-east and Yunnan power grid are simulated and analyzed in 2005 and 2006 year of Southern China power grid in this paper.

先后完成的黄河花园口至东坝头河段1988年中水丰沙型洪水及“92．8”高含沙洪水验证试验结果表明，采用本文提出的模型相似律进行模型设计，模型水流运动、泥沙运动及河床演变规律，均与原型相似。

The test results of this model for the floods of 1988 and 1992 show that the flow pattern, the sediment movement and the channel deformation all conform very well with the field data of these floods.
